Full Review
The PARTU BS-08 is a compact air purifier with an affordable price, which explains its popularity. The company is based in China, but this isn’t a drawback since most components, as well as the entire device, are assembled there — a standard practice in the industry.
This air purifier is designed for small spaces, making it ideal for bedrooms, children’s rooms, small offices, or compact kitchens. It features touch controls located on the top of the unit.
One standout feature of the PARTU BS-08 is its ultra-quiet operation, making it an excellent choice for people who are sensitive to noise while sleeping.
However, one of the most crucial aspects of this air purifier is its CARB certification, especially since it includes a built-in ionizer. This certification confirms that the device complies with California’s strict air quality regulations, allowing it to be sold and used within the state.
How We Tested the PARTU BS-08?
1. For the filter efficiency testing, we used the Temtop LKC-1000S laser particle meter, which measures PM2.5 (µg/m3), PM10 (µg/m3), Particles (per/L), and HCHO (mg/m3) in the air, and also calculates the AQI.
2. We placed the PARTU BS-08 in a 194 sq. ft. (18 m²) room. Then, we recorded the initial air quality values using the Temtop laser particle meter and let the PARTU BS-08 run at maximum speed.
3. After 60 minutes, we measured the new values using the Temtop laser particle meter and saved the data.
4. Using a special noise measurement tool, we tested the air purifier’s noise level at all speeds. We measured the noise level on the dBA scale.
5. Finally, we measured the power usage at all speeds using an energy meter, after which we calculated how much it would cost to use the device at a particular fan speed for one month. For reference, we used an energy price of $0.12 per kWh.

The PARTU BS-08 has a CADR of 61 CFM (104 m³/h), making it suitable for rooms up to 160 sq. ft. (15 m²).
To test its effectiveness, we placed the PARTU BS-08 in a 194 sq. ft. (18 m²) room, which is slightly larger than its recommended coverage area. We ran it at maximum speed and measured the air quality at the start and again after 60 minutes of operation.
Particle Removal Test Room - Comparison
Comparison between the PARTU BS-08 and its competitors in particle removal tests in a 194 sq. ft. (18 m²) room.
The PARTU BS-08 improved air quality by 88% during this test, which is an okay result for such a small air purifier.
However, one notable downside is its underperformance in odor neutralization tests, particularly with strong and heavy odors.
# | Starting Baseline | After 60 min |
---|---|---|
PM 2.5 | 64.4 µg/m³ | 7.3 µg/m³ |
PM 10 | 90.2 µg/m³ | 10.2 µg/m³ |
Particles | 93428 per/L | 10663 per/L |
AQI | 86 | 10 |
Frankly, I believe there are better air purifiers available in this price range. I recommend checking out the Levoit Core 300S or the Medify MA-15, both of which offer stronger performance and better overall value.
For optimal performance, start the air purifier at its highest (third) speed. Let it run at this level for a while, then switch to a lower speed to reduce noise without sacrificing too much efficiency.
Noise Levels Test

9.3 - Average Score (80 products)
10 - Best Score (1 products)
8.2 - Worst Score (1 products)
We use a special noise measurement tool to test the noise level of the air purifier at all speeds. We measure the noise level on the dBA scale.
You can read more about our testing methodology here.
The PARTU BS-08 has three fan speeds but lacks a sleep mode. However, it’s relatively quiet at all speeds.
We used a specialized noise measurement tool to test its sound levels across all speeds. At the first speed, it’s quieter than some air purifiers in sleep mode.
Specifically, it produces just 40.7 dBA at the first speed, making it an excellent option for bedroom use. Additionally, its night light feature adds to its suitability for use in bedrooms.
Noise Levels Test - Comparison
This chart compares the noise levels at the minimum and maximum speeds of the PARTU BS-08 air purifier with those of its competitors.
At maximum speed, it’s slightly louder but still noticeably quieter than many comparable air purifiers. The PARTU BS-08 produces 58 dBA at full speed.
For comparison, the MOOKA B-D02L registers 61.1 dBA at maximum speed, while the Levoit Vital 100S is even louder, reaching 65.4 dBA.
Fan Speed | PARTU BS-08 (dBA) |
---|---|
Speed 1 (Low) | 40.7 dBA |
Speed 2 (Medium) | 47.4 dBA |
Speed 3 (High) | 58 dBA |
Overall, I would say that the PARTU BS-08 is well-optimized for noise and ranks among the quietest air purifiers in its class.
Like other air purifiers in its class, the PARTU BS-08 is a low-power consumer. It uses a 35W motor, although I believe it could have a higher CADR for this level of power consumption.
At the first speed, it consumes only 7.2W, and it draws no energy when in standby mode. At maximum speed, it uses 32W.
In practice, this means you won’t notice much difference in your electricity bill. Running it continuously for 24 hours a day over the course of 30 days would cost about $2.81, assuming an electricity rate of $0.12 per kWh.
Monthly Power Cost – Comparison
Comparison of the monthly power cost at maximum speed between the PARTU BS-08 and some of its competitors.
While the energy cost is minimal, the real expense comes from filter replacements. Unfortunately, since PARTU has been out of business for some time, finding original replacement filters may be challenging.
The good news is that there are plenty of third-party filters available on the market.
Fan Speed | PARTU BS-08 (W + $/month) |
---|---|
Standby | 0W ($0) |
Speed 1 (Low) | 7.2W ($0.63) |
Speed 2 (Medium) | 13.4W ($1.17) |
Speed 3 (High) | 32W ($2.81) |
In my opinion, the PARTU BS-08 could have a better power-to-CADR ratio. However, the difficulty in sourcing replacement filters significantly impacts its overall rating and makes it less affordable to maintain in the long run.
Design
Design is probably the most significant advantage of the PARTU BS-08 air purifier. Black color and impressive touch panel make the BS-08 air purifier very attractive. It is not a dull old box; it is an innovative air purifier with lights and exciting shapes. The night light is handy since you can choose from seven different colors.
It is built with plastic; you can feel matted plastic, which, unfortunately, isn’t of high quality. But then again, this is a Chinese brand, and we know that to fight the competition, you need to be affordable.
The size of the PARTU BS-08 air purifier is small, which means portability. There are no handles to hold it, but even without handles, you can quickly move it. The black color is also disadvantageous for some environments because we know that the black color does not fit all spaces. If the air purifier were white, we could say that it could blend in any environment.
The air intake is at the bottom, and it is small compared to other 360-degree air intake air purifiers. This low air intake means that airflow is not the best and that this air purifier may have trouble in a larger room. The good thing is that air is released on the top, which allows a good spread all over the room.
Touch Buttons
Touch buttons are large enough and very responsive even to the slightest touch. The touch panel is not exactly on the top; it is curved on one side under 45 degrees. With every press of the button, you should hear a beep. This beep sound is confirmation that your order is being served. Some air purifiers are not responding with a beep; I find it natural to have a sound alert and to actually know that something has changed in the way the air purifier is working.
Let’s take a look at what each button does. The power button, as the name says, will bring power, and the air purifier will start working. It will automatically work on the first speed. Also, the lights will be turned on. Fan speed adjustment is used to change the speed from low to medium to high.
Night light, as I already mentioned, is a very nice option that allows you to change the light color. You can choose from seven different colors. As soon as the air purifier starts, the night light is on. Lights are changed in a circle, and once you see the desired light color, you need to press the night light button, and from then, only that color will be on. If you press the night light button again, the night light will shut down. If you hold the night light for 3 seconds, all lights on the air purifier, including the night light, will shut down.
Anion mode is a filtering mode that sends six million anions in the air to clear the air. This mode is, by default off, so you need to press the anion mode button to start it.
Filter replacement light is what most modern air purifiers have. It is used as a visual indicator that will let you know when filters need to be replaced.
PARTU BS-08 remembers last used settings and, on the next run, will start in the same settings. It will work at the same speed; however, lights will always be turned on no matter if on the last shutdown they were turned off.
Size and Dimensions
PARTU BS-08 has 6.6lb and is a kind of light model that can be easily moved. It is also small (9.6 x 9.6 x 17inches), which allows a proper placement even in small spaces like a table, desktop, kitchen table, or any other furniture that can hold an air purifier.
Accessories and Parts
In the package box, you should get one air purifier with a 3 in 1 filter and user manual. Read carefully through the user manual to make sure everything is set right before the first run.
Features Overview
Certified HEPA Removes Allergens
The PARTU BS-08 air purifier uses the HEPA filter, and even if it is small in size it is powerful enough to remove most of the allergens from the air. It can also remove some more abundant viruses, which nowadays is especially beneficial.
Ultra Quiet
The minimum noise on this air purifier is 25dB according to official results; I did my own testing, which you can read under the noise section. We can agree that at low speed with PARTU BS-08, even the light sleepers can get a good night’s sleep.
No Ozone
It emits no ozone when in normal mode. However, when you turn anion mode and six million anions are released in the air, you will probably sense some ozone.
But, even then, ozone levels aren’t high enough to cause any harm, which is confirmed by the CARB certificate. Still, different people react differently to things, so to stay on the safe side, use anion mode when you are not in the room.
Filtration Technology
Filtration with PARTU BS-08 is simple; lousy air is sucked in and pulled through three filters.
The pre-filter is the first filter and removes large particles.
The second filter is the primary filter, HEPA. It removes 99.97% of airborne particles, which means nothing much will be left in the air.
The last filter layer is an activated carbon filter, which eliminates bad odor. Don’t expect wonders in bad odor removal because we know that size of the carbon filter matters.
PARTU HEPA filter captures 99.97% nature allergies, pollen and mold, protect you against running nose and sore throat.
In small air purifiers, activated carbon can’t be large, so odor removal is not the best. But BS-08 air purifier has anion mode, which is excellent against odors.
How to Replace Filter on the PARTU BS-08?
Filter replacement is required when the filter replacement indicator shows an alert, which occurs every six months on average. The process is easy, and everyone can do it.
Put the air purifier horizontally and open the filter cover by turning it counterclockwise. Take the old filter out and put it inside the new one. Return the filter cover back and seal it. And that’s about it.
It is also recommended to periodically use a soft brush and remove dirt from the filter. Never use water or hard tools on the filter. HEPA filters, even with pre-filter, are sensitive, so be careful when brushing.
As soon as you replace the filter, you need to rest the filter indicator by pressing it for 3 seconds. As soon as the light is off, you know that the filter replacement indicator is reset.
For a longer HEPA filter lifespan, you should periodically clean pre-filter.
I’m so annoyed. I bought the Partu BS-08 almost three years ago bc of a California fire close by. After it arrived, we didn’t use it bc we left the area until the fire smoke was gone. I just got it out of storage three months ago. I used it about six hours a day during the past three months. I had cleaned out the filter twice. The second time, 3 days ago. After I put it back together and plugged it in, it wouldn’t work. Nothing. Had a maintenance friend look at it. Won’t turn on. Used very little. No company to complain to. Any thoughts?
Sorry to hear that it stopped working when it is the most needed.
I suggest contacting them on partu4u@outlook.com email or through Amazon. They don’t have a website, and their Facebook page seems inactive, but you can send them a message on Facebook (you might get a positive answer).
